I see several teams that have drafted centers in the 2nd round and the bluechip ones in the mid or late 1st like Ryan Kelly for the Colts. Who gives a shit what other teams are doing, we're talking about how valuable they are to the team.
You know he actually has a point. However it's not that centers are unimportant, they are a key cog of the OL. It's that they are in fact easier to find in the draft. How many tackles in college get converted to center? How about guards getting converted to centers. Now reverse that, how many college centers get converted to guard or tackles? So it's a supply and demand question. If your building a expansion team, you are much more likely to use a high pick on a tackle ( or even guard ) then center. You'll try to find a center later in the draft as a rule, because the pool is larger. Doesn't actually mean they are less important per say, because they are a key cog in the OL, yet there is less urgency to obtain one due to a larger pool to choice from, thus in a way less important.
